To estimate removal rate of phosphorus in aquatic grassland ecosystems of Paldangho, this investigation was conducted along with the coast of a lake. The experimental results may be summarized on communities of Typha angustata, Miscanthus sacchriflorus Phragmites communis and Scirpus tabernaemontani as follows. The annual production of phosphorus for the litters in T. angustata, M saccharsflorus, P. cam-munis and S. taiernaemontani grasslands were 10.252 g /$m^2$, 3.833 g /$m^2$, , 2.656 g /$m^2$, and 5.210 g /$m^2$, respectively. The ratio of annual production of P accumulated on surface soils in a steady state provides estimates of the removal rate r, The estimated removal rates r of P were 0.58, 0.78, 0.68 and 0.59 in T. angustata, M. sacchariflorus, P. communis and S. tabernaemontani grasslands re- spectively. The removal and accumulation of 50, 95 and of 99% of its steady state level, the estimates for P of T. angustata were 1.195, 5.173 and 8.623 years, in M. sacchariflorus were 0.880, 3.842, and 6.403 years, and in P. cammunis were 1.014, 4.390, and 7.316 years respectively, In S. tabernaemontani grassland required period were 1.178,5.099 and 8.500. Key words:T. angustata, S. tabernaemantani, P. communis, S. tabernaemontani, Paldangho, Removal rate, Phosphorus.
